The north is less rainy and snowy, the southern low temperature rains and snows are frozen, and the agriculture and animal husbandry strengthens the cold and antifreeze

It is expected that the cold air activities affecting China will be more frequent in the next 10 days. The temperature in most parts of the country is 1~2°C lower than normal. The rain and snow in most parts of the north are less. There is no precipitation in North China and Huanghuai, and the temperature is low and continuous. The drought poses a threat to the safe wintering of some winter wheat that has not been over-watered in Hebei, Henan, Shandong, and Anhui.

From 16 to 21, there will be a large-scale rain and snow weather in the southern region; southeastern Tibet, southern Sichuan Plateau, northeast Yunnan, north central and eastern Guizhou, southern Hubei, southern Jianghuai, Jiangnan and other places will have medium to medium Heavy snow, some areas have big blizzards. Strong snowfall and low temperature can easily lead to collapse of greenhouses, livestock and poultry houses, and weak young animals.

From 17 to 21, the range of low-temperature rain and snow in the south will be expanded again and the intensity will be strengthened; there will be freezing rain in northeastern Yunnan, southeastern Chongqing, Guizhou, western and southern Hunan, northwestern Guangxi, central and southern Jiangxi. The low temperature rain, snow and ice weather is unfavorable for the growth of winter wheat tillers, rapeseed buds and exposed vegetables, fruit trees, economic forests, etc., which may cause freezing damage or cold damage. Rain and snow will also lead to an increase in the extent of soil over-wetting in most of the south of the Yangtze River, in the northern part of South China and in the southwestern part of the southwest, which will be exacerbated by the normal growth of winter crops and vegetables.

Agricultural advice:

1. Continue to do the cold and anti-freeze work of facility agriculture, animal husbandry and fruit trees. Greenhouse greenhouses should adopt measures such as reinforced scaffolding, thickening cover and artificial heating to keep warm and heat to prevent the occurrence of freezing damage; the pastoral area should prepare enough and timely add concentrate, increase the ability to keep cold, and do a good job in housing reinforcement and cold protection. . Fruit trees and seedlings can be protected from cold and frost by means of soil, tree trunking or white coating, orchard smoked tobacco.

2. In the southern conditional agricultural areas, measures such as applying straw ash, covering straw or film can be used to increase soil temperature and prevent freezing disasters; in over-wet areas, it is necessary to grasp the clear ditch after rain and snow, reduce soil moisture in farmland, and avoid wet stains. Harm occurs.

3. The north has not yet entered the dry wheat field in the wintering period. According to the weather forecast, it will be irrigated in time when the daily average temperature is above 3 °C. It has entered the wheat field during the wintering period, and adopts measures such as applying organic fertilizer and covering to protect and freeze, and ensure the winter wheat is safely wintered.
